Retrospective analysis of immune dysfunctions found in 55 dogs and 62 cats diagnosed with Chronic Fatigue Syndrome (CFS), revealed leukopenia in 11% of dogs (n = 6) and 22.5% of cats (n = 14), lymphopenia in 14.5% of dogs (n = 8) and 10% of cats (n = 6), hypogammaglobulinaemia in 9% of dogs (n = 5) and 13% of cats (n = 8) and thrombocytopenia in 20% of dogs (n = 11) and 68% of cats (n = 42). All patients had creatine kinase enzyme levels above the normal range (CK = 5-100 IU/L) and carried micrococcus-like organisms on erythrocytes. Blood cultures proved positive for Staphylococcus spp. in 16 cases. After low-dosage arsenic-based therapy (thiacetarsamide sodium) all animals experienced complete clinical remission. Subsequent controls demonstrated immune restoration in 4 representative FIV-FeLV negative cats, previously diagnosed with CFS associated with leukopenia, lymphopenia, hypogammaglobulinaemia and thrombocytopenia. The main conclusion is that a CFS-like disease in dogs and cats, characterised by the common hallmarks of high CK levels, absence of known causes of chronic fatigue in animals and presence of micrococcus-like organisms in the blood, can be associated with humoral and/or cellular immune deficiencies in 9-22.5% of cases and with thrombocytopenia in 20-68% of cases. Considerations are made on the possible role of micrococci in the aetiology of the condition and on the similarities with CFS in humans.

Chronic hepatitis C virus (HCV) viremia has been known to provoke a plethora of autoimmune syndromes referred to as extrahepatic manifestations of chronic HCV infection. Aim of the current study was to assess the prevalence of rheumatologic manifestations among Egyptians with hepatitis C infection and its' association with cryoglobulin profile. The current research represents a cross-sectional study where patients with chronic HCV infection attending the outpatient clinic of the National Hepatology and Tropical Medicine Research Institute over a period of 1 year were interviewed. Patients with decompensated liver disease, on interferon therapy, having end-stage renal disease or coexisting viral infection like hepatitis B surface antibody positive patients were all excluded from the research. Laboratory investigations as well as serological assay including cryoglobulin profile, rheumatoid factor, antinuclear antibody, HCV-PCR were performed. Three hundred and six patients having chronic HCV infection were interviewed in this research. The overall estimated prevalence of rheumatologic manifestations in the current research was 16.39%, chronic fatigue syndrome 9.5%, sicca symptoms 8.8%, arthralgia 6.5%, fibromyalgia 1.9%, myalgia 1.3%, arthritis 0.7%, cryoglobulinemic vasculitis 0.7%, autoimmune hemolytic anemia 0.7%, thrombocytopenia 0.7%. Xerophthalmia was significantly present in male population (p = 0.04), whereas fibromyalgia, cryoglobulinemic vasculitis, arthritis, and autoimmune hemolytic anemia were significantly present in female population under study (p < 0.05). In chronic HCV genotype 4 infection, the prevalence of rheumatologic manifestations was 16.3% with chronic fatigue syndrome and sicca symptoms being the most common with no significant correlation to the degree of elevation of liver disease or viral load.
